Thanks for the help Lew!! It worked!!
What I did:
*unhide hidden folders (this was the step that I kept missing. the preference file was hidden!!)
delete preference files
closed application via task manager
deleted locked and renamed the other folders (conflicted folders)
restart and relaunch, load catalog (I had to load catalog with the renamed (colflict) folder for it to work).
And LR is back!! Yay, what a relief. Thank you <3
